Could a rock go though the entire cycle in our lifetime?

Yes, a rock can go through the entire rock cycle within a human lifetime, although this process typically takes millions of years. Rocks can be weathered into sediment, compacted and cemented to form sedimentary rock, or subjected to heat and pressure to become metamorphic rock. Additionally, geological events such as volcanic eruptions or tectonic shifts can accelerate these processes. However, while the potential exists, observing the entire cycle in real time is highly unlikely.
